  5. Recovery from Injury • RICERICE is the treatment for most injuries. It is also useful while you heal. RICE stands for: • 1. rest • 2. ice • 3. compression • 4. elevation

  6. Warm-Up and Cool-Down • Warming UpA warm-up gets you ready for exercise. It increases blood flow and loosens muscles and tendons. • Cooling Down A cool-down helps your body return to normal after exercise. It helps the heart return to its resting rate.

  7. Stretch • How to Properly StretchTo avoid injury, stretch after a warm-up or cool-down. Stretch slowly, without bouncing. Stretches should be held about 10 to 30 seconds.

  8. Don’t Go Too Fast • Know Your LimitsWorking too hard often leads to acute injuries, such as strains and sprains. Long workouts are also risky. The body gets too tired. You can lose concentration and get hurt.

  9. Improve Your Form • Poor FormPoor form may put a lot of pressure on your muscles, joints, and bones. Using poor form over a long period of time can cause chronic injuries, such as tendonitis. • Learning the Correct Form You should talk to your teacher or coach before trying a new exercise. He or she can show you the correct form and help you learn it.

  10. Take a Break • Let Yourself RecoverRest and recovery are important parts of a fitness program. Rest gives the body time to repair itself. Rest should be planned along with exercise in your fitness program.

  11. Wear the Right Clothes • Special ClothingMany sports have special clothing needs. For example, football and hockey jerseys need to be large enough to go over safety equipment. • Consider the Weather Always consider the weather when you are dressing for physical activity. Dress in layers if the weather may change.

  12. Shoes are very important and are often specialized to each activity.

  13. Use Your Safety Equipment • Let Yourself RecoverSafety equipment serves two purposes: • 1. Safety equipment lets you try activities that would otherwise be unsafe. • 2. Safety equipment protects you in activities that are generally safe but in which accidents could happen.

  14. Don’t Exercise Alone • Why Exercise with a Partner?If you get hurt while exercising alone, there probably won’t be anybody around who can help you. If you have friends around, they can help you or go get help.

A flashback is an event in which a hallucinogen’s effects happen again long after the drug was originally taken. • Why Do Flashbacks Happen?
